==Description==
Obtains the Compound Descriptor of a specific USB device. 

==Syntax==
''For access by Device Handle use:''
<pre>
rc = RxUsbQueryDeviceReport(Handle,Report)
</pre>
''For acces by Device Number use:''
<pre>
rc = RxUsbQueryDeviceReport(Number,Report)
</pre>

==Parameters==
; Handle : the Device Handle received from the previous RxUsbOpen. 

; Number : the Device Number from 1 up to the Total Number from RxUsbQueryNumberDevices.

; Report :  receives the Compound Descriptor as hexadecimal string.

==Return Code==
<pre>
0x0000 - NO_ERROR
</pre>
===Errors===
<pre>
0x0057 - ERROR_INVALID_PARAMETER
0x1B58 - USB_NOT_INIT
0xFF13 - ERROR_I24_INVALID_PARAMETER
0xFF1F - ERROR_GEN_FAILURE
0xFF37 - ERROR_DEV_NOT_EXIST
0xFF57 - ERROR_INVALID_PARAMETER
0xFF6F - ERROR_BUFFER_OVERFLOW
0xFFEA - ERROR_MORE_DATA
</pre>
==Remarks==
The Compound Descriptor is the concatenation of Device Descriptor and Configuration Descriptor.  
==Example Code==
<pre>
/* add RxUsbQueryDeviceReport */
rc = RxFuncAdd('RxUsbQueryDeviceReport','usbcalls','RxUsbQueryDeviceReport')
say '+RxUsbQueryDeviceReport(),RC=0x'd2x(rc)

/* invoke RxUsbQueryDeviceReport */
drop Report /* receives device report */
rc = RxUsbQueryDeviceReport(Handle,Report)
say '*RxUsbQueryDeviceReport(),RC=0x'd2x(rc)

/* drop RxUsbQueryDeviceReport */
rc = RxFuncDrop('RxUsbQueryDeviceReport')
say '-RxUsbQueryDeviceReport(),RC=0x'd2x(rc)
</pre>
